This invention relates to mufllers and mufiier assembly.

This invention has utility when incorporated in compactmultiple-diameter mufller' assembly with exhaust or tail pipes or both.

Referring to the drawing:

Figure 1 is a fragmentary view of an embodiment of the invention as amufller for an internal combustion motor of a motor vehicle;

Figure 2 is a detail view on an enlarged scale, parts being broken away,of the assembly feature;

Figure 3 is a view on the line III-I11, of Fig- Figure 4 is an endelevation of a nest of the sections; and

Figure 5 is a distributed view of a two-group nest of the sections.

Motor vehicle 1 is shown having internal combustion motor 2 with exhaustmanifold 3 having exhaust pipe 4 therefrom muflier 6 interposedtherebetween. This muflier 6 is shown as having terminal throats '1 withkerf 8 in each thereof embraced by split collar 9 to be drawn up by bolt10 having spring washer 11 and nut 12 on threaded portion 13 of the bolt10. This bolt is accordingly eiiective to collapse the throat '1 towardthe pipe 4 or 5 in the substantial assembly therewith.

There is quite a range oi sizes for the pipes 4 and 5 in motor vehiclepractice. This muliler 6 is oi universal application due to the adapterring assembly herein disclosed involving a nest of bushings 14,preferably sheet metal and formed of one piece circumferentiallyprovided with stepped split 15 rendering such collapsible. Furthermore,radial projections are present in each member forming terminal or stopmeans preferably in the form oi wings or prongs 16 providing adecorative feature as well as utility in that the mufller 6 whensupplied to the dealer has assembled therein the nest of these bushingsections, the flanges or radial projections serving to deiine orposition the several bushings of each section.

The garage man or one making the assembly has the muiiier 6 in positionto slip over the pipe 4 and in the event the pipe 4 be too large, anedged tool as, ior example, a screw driver may be thrust back of a wingorflange 16 of an inner bushing or bushings thus give the next largerdimension for the adapter interior. When this dimension closelyapproximates the external diameter of the-pipe, it may be thrust thereonfor slight frictional 1,890,151, dated 449,516, May 3, 1930.

singing with tail pipe 5 andto slip such out and by To- December 6,1932,

gripping due to the taper at the flange region or it may even have aneasy slip flt.

The various bushing sections 14 as nesting together have the steps 15slightly open in their normal position and the steps are preferablystaggered as to each other, thereby providing a sealed coupling. Withthe pipe thrust into the throat through the bushing sections, tighteningof the nut 12 on the bolt 10 may effect such. frictional clamping atthis collar 9 so as not only to make the assembly tight againstwhistling or from gas or air blowing, but for substantially positioningor supporting the mufller between the pipes. There is according yprovided herein a universal muifler and connection arrangement ofcompact type adaptable for a plurality of diameters of exhaust and tailpipes, which muflier arrangement may be readily installed over a rangeof sizes for the pipes whether similar or dis-similar.

What is claimed and it is desired to secure by Letters Patent is:

1. In a nest oi bushing sections comprising sheet metal rolls of splitring form, said rolls terminally having a toothed flange forming a rimfor each thereof, said rims in nesting assembly of the sections being inabutting relation for imparting arc flexibility to the separate rings,and the teeth of the successive rims providing abutment means eflectingready relative, shifting between the s. r A 2. In a device of the classdescribed, a plurality of sheet metal members of-"substantiallycylindrical configuration each member having projections extendingradially from one end thereof; said members adapted to be assembled innested relation, said radial projections serving to limit adapted to beengaged by a tool for the position of the members in nested relation. I

3. In a'device oi the class mlity of split tubular members, each memberhaving a stepped split and a projection, extending radially from one endthereof said members having different diameters and adapted to beassembled in nested relation, the radial projections of the members innested relationship deflning the position of said members with respectto each other.
